Abstract: An improved ceramic heater to be incorporated in a glow plug is described.   The heater is made up of a ceramic core enclosed by 2 ceramic layers sintered together to form a unitary ceramic heater.   All  three component elements of the heater are composed of silicon nitride containing different concentrations of an electrically conductive ceramic substance, such as titanium nitride, titanium carbonitride or molybdenum disilicide.   Each component additionally contains low amounts of sintering additives.  The core of the heater, is a ceramic rod which has  the  highest  concentration  of  the  electrically conductive substance.  The core is enclosed in a ceramic layer which is an electrical insulator and is composed of silicon nitride, less than 28 vol.% of the electrically conductive ceramic substance and sintering additives.  The second layer over the core contains the electrically conductive ceramic substance in a concentration which is in between that in the core and that in the insulator layer.  One end of the rod is integrally connected to the second layer over it.  The ceramic heater is fitted into a glow plug housing.   The core and the second layer properly joined to appropriate connectors in the glow plug housing form an electrical circuit when connected to an electrical power source.

Patent CA-2138685-C (CA)
Title: Shade operator
Inventor: NIJS FREDERIK G J
IPC: E06B9/78
Filed: 1994-12-21
Granted: 1997-06-17
Abstract: An operator for a window or like shade serves to turn a shade roller to a new desired position as the result of a torque applied from a manually operable source, such as a chain operated wheel.  The device includes a helical spring that is seated within a fixed bushing with its outer surface in contact with an inner cylindrical surface of the bushing. When torque is applied from the manually operable source, one overlapping end of the spring is moved away its other end to reduce the spring diameter and hence release any frictional engagement of the spring with the bushing, thus allowing the torque to rotate the spring, which rotation is transmitted to the roller.  However, when no such manually applied torque is present, the spring and the roller remain effectively locked in position.  Any torque applied from the roller due to the weight of a partly lowered shade acts to tend to increase the spring diameter and thus to ensure a binding frictional engagement between the bushing and the spring.
Patent CA-2150959-C (CA)
Inventor: NEBLETT IAN GLENN
IPC: F04C29/12
Filed: 1995-06-05
Granted: 2005-05-24
Abstract: A system having a matched vane compressor and impeller is described for use in either a hydraulic system or in a two phase air conditioning system.     The impeller is matched to the compressor to return work to the compressor through a shaft or gearbox. The compressor is a vane compressor having longitudinally reciprocating vanes carried in a slotted disc between matched, opposed cam faces forming a series of variable geometry chambers which draw in and expel working fluid during rotation of the shaft. Compression is achieved by exposing the fluid in the chambers to high pressure fluid while the volume of the chamber is not changing. A pressurizing port is placed tangentially to the chambers for this purpose. The impeller also makes use of tangentially disposed pressure ports to expose the turning pockets of a drum to higher pressure. The outlet of the impeller only skims off a surface layer of the liquid in the pockets, reducing the volumetric through flow of the impeller while it returns work to the compressor. These systems can be utilized in hydraulic or thermal applications.
